Audio only coming out of right speaker

Hi,
I recently bought two Polk T15 bookshelf speakers to connect to my PC. I bought an ONEU super bass AMP to power them as well. When I set up the speakers and connect them to my phone, they sound excellent and both speakers work, however, when I connect them to my PC, only the right speaker works. The left isn't completely mute, instead, it has a crackling sound coming out of it. It sounds like the typical noise you get when you half plug in the audio jack. I am plugging the audio jack into my computer's soundboard which is part of the motherboard.

How can I fix this? I've heard the problem might be with the Realtek drivers, so I removed it, but the problem persists. Is it a hardware failure?

Computer specs:
Asus Maximus VII Hero Motherboard
Intel Core i7 4790k CPU
NVIDIA GTX 970 Graphics Card
Windows 64 Bit

Audio:
High Definition Audio Device
NVIDIA High Definition Audio
Realtek High Definition Audio

Yeah, I tried plugging in a pair of earbuds and the same issue persists. The audio comes out of the right earbud and the left one just crackles. As for the jack at the front of the case, the connector doesn't fit for some reason. It's like the jack on the headphones is too long for the port. Thoughts?

I have a Maximus VIII Hero motherboard in my system.
What is the "High Definition Audio Device"? That is a generic Windows sound driver, but for what?
Check the Playback device panel. The "Speakers" (Realtek) should be set as default playback device. You can test the speakers in the Playback panel.

Open the Realtek HD Audio Manager and check the Left/Right balance and make sure it is in the center position.

The front panel headphone jack is made for a regular 1/4" stereo plug. I assume you are plugging into the GREEN speaker jack on the rear panel and not a different jack.

Ok, the "High definition device" were my speakers because I had uninstalled Realtek drivers. Since then, I have re-installed it and it has replaced "high definition device" with "Realtek High Definition Audio," which is the new name for my speakers.

I am indeed connecting the audio jack to the green port at the back of the PC. Would an adapter from phone peripherals to PC peripherals fix the problem here? Thanks!

Since you are using Realtek, uninstall the High Definition entry in the Device Manager, just to avoid any potential conflicts. It probably won't affect your problem, but get rid of any potentials.

Not sure what you are referring to. If the headset is designed for a phone, yes an adapter as previously noted is needed.

Also, disconnect the small power amp when testing with the headset. That power amp was originally designed for car audio, but I suppose can be made to work with the PC. Did the PC audio work OK before connecting the power amp? (If it did, the power amp may have caused the problem). A lot of "if's".

Ok, I'll try to remove the High Definition audio.

I think it might help if you know my entire audio setup.

I've sent back the ONEU miniAmp because when I had the speakers on, no matter what volume there was a buzz in the background. Should I try a different amp?

"Stereo" speakers make poor PC speakers as they are not internally shielded and the PC can emit some RF interference which will be heard (possibly as a buzz) in the speakers. It sounds like you are trying to save money and use what you have but best option is to get a set of "Computer" speakers. I've seen PC speakers for as low as $10 (they are $10 speakers but if you want inexpensive they would work).
